My tabs crash all the time. Sometimes it'll go a while without crashing, other times it's literally every two seconds. Particularly if I'm doing anything that doesn't autosave. Thanks. Sometimes it's just whatever tab I'm on (or occasionally I'll click on one I've had open in the background only to discover it crashed at some point, other times (and not infrequently!) it crashes the entire browser. Sometimes when it does that, it also logs me out of everything for no particular reason as a little sadistic cherry on top. The passwords are still saved I'm just logged out of EVERYTHING. A few times, it seemed to have made my bookmarks go away, but force-stopping it and re-entering made them reappear, so they weren't deleted. I don't know what's going on but I'm at my wit's end. The crash reports mostly just say EXCEPTION_ACCESS_VIOLATION_WRITE (I haven't checked every single one individually since there's too many, but the ones I've clicked on all say that as far as I recall). If this keeps up I'm going to have to switch browsers or something because I'm actually losing it.

Firebird is so slow now, that I can rarely receive the code that you send me. Have to take annother programm for that. Freezes even when trying to mark a mail or erasing it. WIN 11. The programm is working well at my wifes laptop also WIN 11. 2 month ago it worked fast and fine. Working in Troubleshooting mode does not show any spam ordner like before and it does not run better. I also downloaded the last version. No change! I would like to uninstall the programm but did not dare due to perhaps loose all my mails. Could you help me please? Thank you!

Tabs will crash over and over again. I can barely look at any given page for longer than a minute or two. What happened?? Firefox was never like this before. It just crashed in the middle of me typing this LMAO. Using Brave in the meantime. This is ridiculous.

Just got my repaired laptop back. Windows Home 23H2 build 22631.6199. Installed Firefox, synched my account. Firefox or a firefox tab have crashed 19 times in the last 3 days since the fresh install.

Actually crashed while preparing this message. What to do?

Program keeps crashing. I am running the latest version with windows 11. I have even ran in troubleshoot mode with everything disabled and still crashing. It wont even submit the crash report is says it failed. Here is the crash report it gives me.

mozilla keeps crashing almost on every website (says the tab has crashed). I checked, mozila is up to date, all extensions removed, no viruses or spyware, and it is crashing in troubleshoot mode as well.

Also few times a day says "your device ran in to a problem and needs to restart). Please advise what to do? Here is a submitted crash reports:

Whilst using TB the screen went white with dozens of little tabs along the top of the screeen with what look like page icons, as the app became 'not responding'. Re-loading didn't help - same screen. Re-starting didn't help. I uninstalled and re-installed TB but it is stil the same. Opening in Windows (11) safe mode produced virtually the same result except for a few seconds I was able to open the hamburger menu and select trouble shooting. Opened in trouble shooting mode showed several alerts of 'failed to connect with servers' (outlook.office365.com imap.gmail.com and Yahoo). Then it shut down as before 'not responding'. When open, TB is using some 80% of available memory., and I can only close it by using Task Manager. I'm a complete dunce at this stuff so, if anyone knows a way out of this hole, please use simple English! Thanks, Jeff

I just installed Thunderbird and it opened with the Welcome to Thunderbird (donation request) page.

BUT I can't DO anything in the app like setup an email address or access settings because the hamburger menu button does nothing when I click it. I can't click anything that will let me actually do anything. It's essentially a brick out of the box.

Could my antivirus or firewall perhaps be interfering with it? Seems unlikely since the problem is within the app itself and not a connectivity issue but I can't think of anything else and there aren't support articles on this fundamental problem.

I'm running Windows 11 with all updates. I tried restarting the app but no change. Any idea what's going on and how to fix it? Thanks.

Tbird still displays No message found, does not allow user control, then starts "Not responding." In can only hit the top right, red X, and close the program. The same happens when I start in Troubleshoot mode. I'm running Windows 11 with the latest updates. Is something wrong with my profile?? What can I try next?

The attached image shows the error message I get when I try to run Thunderbird. This has been the case for several months, and all of the suggestions I've found online have failed to make any difference at all.

It seems this must be a fairly common error with other software, but within Mozilla's help menus I could find only one thread of two messages that addressed it at all, with no solution offered.

I'm running Windows 11, and have had no problems with Thunderbird until this one.

I hope someone can offer a solution that works for me.

Thanks,

Neil Farrell

Firefox crashes randomly during video playback. I've submitted over 10 crash reports. Here's the two latest crash report (which includes my device's hardware information): https://crash-stats.mozilla.org/report/index/81eb1750-1dd0-490d-9eb1-d3c2c0250224 https://crash-stats.mozilla.org/report/index/6682a7f2-836a-4365-938e-c9ab20250224

I'm on Fedora 41 + gnome, but this issue persisted even in Windows 11, which caused BSOD therefore I made the switch to linux (At least in linux it doesn't crash the whole system, only firefox). If you need any additional information let me know. I can run journalctl/dmesg if required.

I've already tried things like restarting in safe mode (troubleshoot mode), refreshing firefox etc. Didn't work.

Thanks in advance!

I'm trying to use Booking.com to pay online for a holiday and Firefox keeps crashing as soon as I press confirm payment. Have tried several times using 2 different cards. What can I do?

I posted this earlier and the bot named David is trying to take over with ideas that don’t work. How do we stop it? I also posted from my own email and it tried to stop me.
